“…Plant roots may collect petroleum pollutants in the soil, transport them to leaves and fruits, and store them, as well as transmit pollutants from leaves to roots. Corn germination rate, plant height, leaf area, and dry matter yield were all drastically reduced as a result of petroleum contamination [58]. Plant growth is slowed, stem length and diameter are shortened, aboveground tissue length is reduced, and the root length and plant leaf area are altered due to a lack of oxygen and nutrients in the polluted soil (depending on the plant species) [59].…”

The petroleum industry’s development has been supported by the demand for petroleum and its by-products. During extraction and transportation, however, oil will leak into the soil, destroying the structure and quality of the soil and even harming the health of plants and humans. Scientists are researching and developing remediation techniques to repair and re-control the afflicted environment due to the health risks and social implications of petroleum hydrocarbon contamination. Remediation of soil contamination produced by petroleum hydrocarbons, on the other hand, is a difficult and time-consuming job. Microbial remediation is a focus for soil remediation because of its convenience of use, lack of secondary contamination, and low cost. This review lists the types and capacities of microorganisms that have been investigated to degrade petroleum hydrocarbons. However, investigations have revealed that a single microbial remediation faces difficulties, such as inconsistent remediation effects and substantial environmental consequences. It is necessary to understand the composition and source of pollutants, the metabolic genes and pathways of microbial degradation of petroleum pollutants, and the internal and external aspects that influence remediation in order to select the optimal remediation treatment strategy. This review compares the degradation abilities of microbial–physical, chemical, and other combination remediation methods, and highlights the degradation capabilities and processes of the greatest microbe-biochar, microbe–nutrition, and microbe–plant technologies. This helps in evaluating and forecasting the chemical behavior of contaminants with both short- and long-term consequences. Although there are integrated remediation strategies for the removal of petroleum hydrocarbons, practical remediation remains difficult. The sources and quantities of petroleum pollutants, as well as their impacts on soil, plants, and humans, are discussed in this article. Following that, the focus shifted to the microbiological technique of degrading petroleum pollutants and the mechanism of the combined microbial method. Finally, the limitations of existing integrated microbiological techniques are highlighted.

“…The relationship between light crude oil spillage and fertilizers usage on cropped farmland ( 32 ) indicated that an increase by a unit of fertilizers usage on light crude oil spilled crop farms resulted in a reduction of output by 0.729 units (statistically significant at 10%). These results showed that fertilizers usage had no expected positive effects on crops production on crude oil polluted areas and hence did not lead to expected increase in yields/output (Uzoho et al, 2004;Dung et al, 2008;Okonwu et al, 2010;Fernandez Luqueno et al, 2012).…”

“…The interaction between labour and fertilizers ( 26 ) indicated that a unit increase in the inputs, resulted in a reduction in output by 0.283 units in crude oil polluted crop farms, which was statistically significant at 1%. This could be that on a crude oil spilled crop farm any increase in land, labour, and fertilizers or improved seeds are wasted because of the detrimental effects of crude oil pollution (Uzoho et al, 2004;Dung et al, 2008;Okonwu et al, 2010;Fernandez-Luqueno et al, 2012).…”

This study researched on crude oil pollution effects on crop farms in Rivers State, Nigeria using stochastic translog production function. Data were collected in the state, using multi-stage sampling technique. A total of 296 structured questionnaires retrieved from farmers in crude oil polluted and nonpolluted areas of the state were used. Stochastic translog production interaction between land and heavy, medium and light oil spillages resulted in crops output reduction by 0.255, 1.257 and 1.027 units, respectively. Interaction across heavy, medium and light oil spillages and fertilizers usage indicated farm crops output decrease by 0.805, 0.586 and 0.729 units, respectively. This study therefore concluded that crude oil pollution on crops farms reduced crops output significantly, hence detrimental to crop production in Rivers State, Nigeria.

This study examined the household level factors affecting the intensity of crop commercializationa and its impacts on livelihood of smallholder farmers. The study was conducted in six villages/tabias b in the Tigray Region, Ethiopia. The estimated results showed that ownership of oxen, amount and quality of yield harvested, and training on crop marketing have a positive and significant effect on intensity of crop commercialization. Outstanding debt and off-farm income were also identified among the driving forces of increased crop commercialization. However, family size, shortage of family labor, unreliable rainfall, costs of farm inputs such as fertilizers, crop pests and diseases, distance to market have a negative and significant effect on the intensity of crop commercialization. The study results indicated that the average crop commercialization index was about 19% of the total produce in the study area which shows the livelihood of the smallholder farm households is almost subsistence oriented. The crop commercialization index for cereals was lower than that of pulses and vegetable and fruits production, implying that in the dryland areas of Ethiopia, cereal production is more of subsistence nature than pulses and horticultural crops. Nevertheless, participation in crop commercialization has a positive and significant impact on smallholder livelihoods through improved income and asset holdings.
